Hi @kl0u
Thank you for your suggestions.
I don't have a concrete solution yet, but I can try to fill the gaps in
testing and see if I can come up with a better solution.
Speaking about testing. Can you think of any other test cases that I might
need to cover?
i) Seems like a good idea. I'll add more testing and see if it can help
ii) Good point. I'll work on this.
iii) I am not sure why NFA must be changed? I think we can build NFA using
current state types by adding necessary transitions around optional states.
What do you think?
